1. Key 5 will now read VNAV OFF and there is a new VNAV message

box.

2. If the DESCEND IN counter is greater than 00:00, the new message

box will show DESCEND IN with the counter value.

3. When the DESCEND IN counter reaches 00:00, the alarm will sound

and a message will be displayed across the Screen saying START

DESCENT NOW. Key 5 will change to ALARM OFF then back to VNAV

OFF. Once Key 5 is hit or the alarm times out, the START DESCENT

message will disappear and the VNAV message box will now show

ADVISORY ALT: XXXXX ft and count down. The descent angle will be

fixed at this point to prevent changes in ground speed from altering the

descent profile.

When the advisory altitude is within 500 feet of the TO altitude, the alarm

will sound again and a message will be displayed across the Screen

saying FINAL ALT IMMINENT. Key 5 will change to ALARM OFF then

back to VNAV OFF. Once Key 5 is hit or the alarm times out, the advi-

sory altitude will continue to count down until it reaches the TO altitude.

VNAV mode will then cancel automatically.

Should you wish to perform a DIRECT TO or select a new Flight Plan

the VNAV Mode will need to be cancelled.

VNAV can be used for climbing as well as descending. If the FROM alti-

tude is set to a lower value than the TO altitude then everywhere the

words DESCENT and DESCEND appear, the word CLIMB will be used

instead.
